ACHILLE BATAILLE, OF NEW YORK, N. Y.

PIPE JOINT O R COUPLING.

SPECIFICATION forming part of Letters Patent No. 230,606, dated August 3, 1880.

Application iled December 26, 1879.

To all whom t may concern:

Be it known that I, ACHILLE BATAILLE, of

an Improvement in Pipe-Joints, of which the following is a specification.

In an application for a patent heretofore made by me a flexible joint for pipes is set forth. My present invention is an improvement upon and modification of the same.

1l make use ot' an annular chamber around the inner portion of the coupling devices for the pressure to act between the two parts of the coupling and keep them in contact to form a tight joint, at the same time the parts can be turned the one on the other, so as to allow the necessary freedom of motion to adapt the joint to the tubes on railway-cars for the airbrakes or for other tubes, wherever available.

In the drawings, Figure l is a longitudinal section of the joint, and Fig. 2 is a cross-section at the line .r fr. and Fig. Bis a section of a modification of this joint.

The tubular portion c of t-he joint is to be connected with the hose or pipe, and around it is the conical hearing b for the ring;` c, the interior ot' which ring is conical and adapted to iit the bearing b, and these conical surfaces should be ground together so as to be water or air tight. The cap eis attached to the ring c, and it is provided with a tubular portion, f, to which the pipe or hose is connected.

There'is a cylinder, g, within the coupling at the end ot' the conical portion b, and the cap c is provided with a ring, 7L, that is connected by the arms -i with the cylindrical ange 0 otl this cap c, and said ring h forms a guide around the cylinder g to hold the respective parts of the coupling in their'proper relation axially to each other, so that they may-be turned freely the one on the other, but not become separated. The pressure of the liquid or iiuid within the joint acts between the inside of the cap e and the iiat end of the cone b to press the conical surfaces together endwise of the coupling, and the arms i do not interfere with the pressure reaching and acting upon this iiat end ofthe cone b and I remark that it' desired a washer of leather or similar material may be introduced between the ring h and the end of the cone b, and between the cap c and coupling c, where they are bolted together.

The parts are free to be turned or to accommodate themselves to th eirrespective positions when there is not any pressure within the joint; but when the pressure is admitted the conical surfaces ot' b and c set together so closely as to form a tight joint, at the same time the parts can be turned one on the` other, it' required.

ln Fig. 3 the parts correspond in construction and operation with those in Fig. l, the only differences being that the pipes a and f turn olf laterally, instead of' being in line with the other portions ot' thejoint. This renders it necessary to make the conical ring b separate from the portion a, and introduce the same into the couplin g-ring c after it has been placed upon the other part ot' the joint, and secure this ring b byscrews 3 or other suitable fasteniugs. Y

If desired, the arms 11, that secure the ring h to the cap c, may stand at an inclination, as shown in Fig. 3, instead ot iiat, as in Fig. 1.

The guard-rin g s and washer may be applied around the pipe a and secured thereto at the end ot' thejoiut c, so as to prevent the tube c sliding into the joint c accidentally and separating the conical surfaces.

I claim as my invention- 1. The combination, with the coupling-tubes af, ot' the conical bearing b, ring c, cylinder g, cover c, arms fi, and ring It, substantially as set forth, whereby the pressure acts within the annular portion ooi' the joint to keep the parts c and; b together, substantially as set forth. v f

2. The guard-ring s, in combination with the coupling-ring c, pipe c, cone b, and cap c, substantially as kset forth.

Signed by me this 20th day ot December, A. D. 1879.
